D) TROUBLE SHOOTING
1) YOUR CB RADIO WILL NOT TRANSMIT OR YOUR
TRANSMISSION IS OF POOR QUALITY:
- Check that the antenna is correctly connected and that the SWR is properly
adjusted.
: 40
: AM/FM
: from 26.965 MHz to 27.405 MHz
: 50 ohms
: 13.2 V
: 150 (L) x 165 (H) x 45 (D)
: 1.2 kg
: Microphone with support, mounting
cradle, screws
: +/- 300 Hz
: 4 W AM / 4 W FM
: inferior to 4 nW (- 54 dBm)
: 300 Hz to 3 kHz in AM/FM
: 1.0 mV
: 1.7 A (with modulation)
: 1.8 %
: 0.5 µV - 113 dBm (AM/FM)
: 300 Hz to 3 kHz in AM/FM
: 60 dB
: 5 W
: minimum 0.2 µV - 120 dBm
maximum 1 mV - 47 dBm
: 60 dB
: 70 dB
: 500 mA nominal
800 mA maximum
- Check that the microphone is properly plugged in.
- Check that the programmed configuration is the correct one (see table p.
xxx).
2) YOUR CB RADIO WILL NOT RECEIVE OR RECEPTION IS POOR:
- Check that the squelch level is properly adjusted.
- Check that the volume is set to a comfortable listening level.
- Check that the microphone is properly plugged in.
- Check that the antenna is correctly connected and that the SWR is properly
adjusted.
- Check that you are using the same modulation mode as your correspondent.
- Check that the programmed configuration is the correct one (see table p.
xxx).
3) YOUR CB WILL NOT LIGHT UP
- Check the power supply.
- Check the connection wiring.
- Check the fuse.
E) HOW TO TRANSMIT OR RECEIVE A MESSAGE
Now that you have read the manual, make sure that your CB Radio is ready
for use (i.e. check that your antenna is connected).
Choose your channel (19, 27).
Choose your mode (AM/FM) which must be the same as that of your cor-
respondent.
Press the «push-to-talk» switch and announce your message «Attention sta-
tions, transmission testing» which will allow you to check the clearness and
the power of your signal. Release the switch and wait for a reply. You should
receive a reply like, «Strong and clear».
If you use a calling channel (19, 27) and you have established communication
with someone, it is common practice to choose another available channel
so as not to block the calling channel.
F) GLOSSARY
Below you will find some of the most frequently used CB radio expressions.
Remember this is meant for fun and that you are by no means obliged to
use them. In an emergency, you should be as clear as possible.
